Product Description
Switchgear is an indispensable component of modern electrical systems, designed to seamlessly handle the operations of opening, closing, controlling, and safeguarding electrical equipment across various stages of power systems: from generation to transmission, distribution, and energy transformation. This robust equipment ensures reliability and efficiency.
Structure
High Voltage Switchgear: A sophisticated assembly often comprising a busbar room, a circuit breaker room, a secondary control room (also known as the instrument room), and a feeder room, each compartment smartly isolated by sturdy steel plates for optimal safety. In the KYN28A-12 model, the design is meticulously structured with the instrument room on top, the circuit breaker room centrally located, and the cable room at the bottom, exemplifying a harmonious blend of functionality and safety.
Low Voltage Switchgear: Ingeniously categorized into fixed and drawer types based on component installation methods. The drawer type is particularly noteworthy, featuring a fixed cabinet body paired with a movable device part, offering unparalleled flexibility and ease of use.
Internal Components
The heart of the switchgear consists of vital components: circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices, all designed to work in concert to ensure operational excellence and safety.
Classification
Switchgear Classification: Based on circuit breaker installation method, they are divided into movable and fixed types. Cabinet structures include open, metal enclosed, and metal enclosed armored types. Voltage levels distinguish them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. Furthermore, they differentiate into AC and DC switchgear based on voltage waveform, and by purpose into incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: Crafted to masterfully connect and disconnect circuits, this technology enables precise start-stop control of power equipment, ensuring efficiency and operational command.
Protection Function: Ingeniously designed to automatically sever the circuit in instances of overload, short circuit, or leakage, thus providing a safeguard for both equipment and personnel, enhancing safety and reliability.
Application Location
Versatile and reliable, the switchgear is ideal for a diverse range of locations including power plants, substations, petrochemical facilities, metallurgical steel rolling mills, light industry textile factories, residential areas, and high-rise buildings, ensuring robust performance across industries.
